ADAMS RITE 4104-02 Door Lock Mounting Bridge

Method "A" spans the stile with a steel bridge at the top and bottom of the lock.

A simple handle (Adams Rite Installation Tool 4075) is used to position the bridge accurately in the stile while its two screws are tightened to form a "web" in the door. Resilient washers allow for minor adjustment to fit the lock flush in the door.

Lock mounting methods for narrow stile aluminum doors - the most prevalent methods of mounting locks and latches within the hollow tube stile of glass doors are shown in the accompanying illustrations.
